Chapter 4 Application

4.1 Network Requirements

The company has established the server farms in the headquarters to provide the Web, Mail and FTP

services for all the staff. The dedicated line access service was used by this company, which costs

greatly in network maintain and cable layout. With the business development of the company, it’s

required to establish an effective, safe and stable network with low cost for this company. The detailed

requirements are as follows:

¾

Internet Access

This company has terminated the dedicated line access service but maintained one dedicated

line as the backup line, and has applied a high-bandwidth Fiber Access as the main line.

¾

Network Management

To avoid some of the staff using IM/P2P application at the working time to occupy a lot of

network bandwidth, it’s required to implement the online behavior management and to specify

the network bandwidth limit for each staff member.

¾

Network Security

This enterprise network should be able to defend the common attacks from the internal or the

external network, such as ARP Attack and DoS Attack. Moreover, the real-time monitoring on

the network traffic is required.
